Can't perform an HTTP VM install with virt-manager

Status changed to 'Confirmed' because the bug affects multiple users.

Seems the same bug that affected RedHat:
https://bugzilla.redhat.com/show_bug.cgi?id=1058720

According to that report it is fixed in upstream code, so should reimported.

It renders essential functionality of the package (or a dependent one) broken.

Looks like cherrypicking commit bd15cd3d6e should fix this

It seems this actually is in the virtinst package.

I was going to push this patch, however while it gets us past the error reported in this bug, it proceeds to get the kernel and initrd then tell me: Unable to complete install: 'invalid stream pointer in virStorageVolUpload'

FWIW, this is what I am getting on Trusty with virt-install:

I am available for testing.

 virt-install -l http://ftp.ubuntu.com/ubuntu/dists/trusty/main/installer-amd64 -r 1024 --accelerate -n x1 -f /home/ubuntu/x.img

is the command i'm using to reproduce.

This is the command I used in comment #8. My gripe is how to continue using preseed since --extra-args is incompatible with --cdrom (i.e. when using the 'ISO workaround').

virt-install -d \
        --virt-type kvm \
        --hvm \
        --accelerate \
        --connect qemu:///system \
        --os-type linux \
        --noautoconsole \
        --graphics vnc \
        --network bridge=br0 \
        --vcpus $CPU \
        --os-variant $VARIANT \
        --name $NAME \

        --extra-args="locale=en_US interface=eth0 DEBCONF_DEBUG=developer auto=true priority=critical $PRESEED"

(bumped prio given pmatulis' description of the need for this)

This bug was fixed in the package virtinst - 0.600.4-3ubuntu2

virtinst (0.600.4-3ubuntu2) trusty; urgency=medium

  * cherrypick upstream patch to fix volume upload (LP: #1286500)
